This is a Nitori low-rebound mattress topper. I used it only once, but it didn't suit my body, so I'm selling it. I only used it once, but it has been stored by a private individual, so please be aware of that if you are concerned. I have discarded the outer packaging, so it is not included. There were creases from when I purchased and opened it, but they gradually disappeared after leaving it for a few hours.
